Assessment of Ozone, Nitrogen Oxides, Air Particulate Matter in the Ambient Air of Nairobi city
Mangala, JM; Odhaimbo, GO; Kinyua, AM; Gatebe, CK; Maina, DM (2006)World wide, more than 1.1 billion people live in urban centres that are highly polluted by industrial and other human activities. Among the most common and most virulent air pollutants are sulphur dioxide,suspended particulate ... -
he Impact Of Environmental Lead Poisoning On Iron And Haemoglobin Status In Kenya
Maina, DM (Nuclear Science & Technology, University of Nairobi, 2005)Food crops are an important source of minerals that are important to the health of human beings. The main source of these minerals is the soils that they are grown in. The quality of these soils is ameliorated using additives ... -

Ionomic variation characterization in African leafy vegetables for micronutrients using xrf and hplc
Akundabweni, LSM; Maina, DM; Mulokozi, G (Nuclear Science & Technology, University of Nairobi, 2010)Beside the phytochemical, ionomic fingerprinting represents the inorganic trace element composition of the cellular and organismal component. High-throughput elemental analysis technologies, such as X-Ray Fluorescence ... -
Lead Concentration In Milk And Cereal Products Commonly Consumed In Kenya
Maina, DM (Nuclear Science & Technology, University of Nairobi, 2005)Environmental pollutants arise from many sources, and exposure may occur through different routes. Some pollutants of particular concern are airborne substances, which occur primarily in suspended particles. These include ... -
Mineral micronutrient density in local cereals sampled from Bungoma, Maseno and Kibwezi areas
Akundabweni, LSM; Munene, RW; Maina, DM; Bartilol, SK (2010)Cereals constitute a food staple in the African bread (Ugali) form. Overdependence on maize as a predominant staple is partly blamed on the constricting indigenous cereal phyto-diversity. Strategies rekindling interest ... -
Monitoring of suspended particulate matter (SPM), heavy metals and other parameters in some workplaces
Kinyua, AM; Gatebe, CK; Mangala, MJ; Korir, AK; Bartilol, S; Maina, DM; Mugera, WG; Kamau, GN; Chakaya, JM; Karama, M; Miungu, DM; Kitio, V (2000)This report presents results of measurements of sound levels, chemical analysis of air particulate matter and soil samples from two factories in Nairobi. A preliminary assessment of suspended particulate matter (SPM) in a ... -
Natural gamma radiation levels, indoor and water 222 RN Concentrations in soil division of Kerio valley, kenya
Nderitu, SK; Maina, DM; Kinyua, AM (University of Nairobi, 2001)Human beings are constantly exposed to natural radioactivity. This radiation is mainly from natural gamma rays and radon and its decay products. The gamma rays are as a result of the decay of primordial nuclides and their ... -
